consumption of unspun material wound thereon.

In the particular type of spinning machine to which the invention relates the unspun ma- 7 terial commonly called ropingis carried 103 upon jack spools which rotate upon a horizontal axis in the upper portion of the machine. The spools employed in this type of machine contain a large number of ends of roping and therefore are quite heavy and bulky. Heretofore a heavy burden was'imposed upon the operative who had to be tall and muscular to manipulate the spools into their running position and remove the empty ones. The general object of the present invention is to facilitate the handling of the spools when replenishing the machine with unspun material.

A further object of the invention is to provide a. means for readily removing empty jack spools from the machme by lifting one end thereof a short distance and removing its gudgeon laterally from its bearing slot, and then removing the other gudgeon longitudinally from its bearing slot.

A further object of the invention is to permit removal of one or both of the spool gudgeons laterally from their. hearing slots, and to retain the spool gudgeons'in their respective slots when a full spool of roping is lowered into running position.

Other objects and features will appear more fully from the following specification in connection with the accompanying drawing and will be pointed out particularly in the claims.

The present invention is applied to the mechanism at the upper portion of a spinning frame. which mechanism supplies the unspun material commonly called roping to the spin ning mechanism. The particular type of spinning machine to which the invention is adapted receives its supply of unspun material from jaelrspools upon which is wound a mass of roping containing a comparatively large number of roping ends. There are usually a plurality of such spools disposed horizontally in the machine and placed end to end either in a single row or more commonly in a double row, one row supplying the spindles on one side of the machine and the other row supplying the spindles on the other side.

The jack spools are rotated to feed the roping ends by frictional engagement with co-operating driving drums situated below the jack spools and driven from some convenient rotating element on the spinning machine.

The ends of the spools are provided with gudgeons which project into substantially vertical slots in a plurality of upstanding brackets mounted on the machine. The upper ends of the brackets are provided with upward and outward projecting arms at the ends of which are situated notches or bearings to receive temporarily the gudgeons of a full spool and permit the operative to separate the various ends of roping before the spool is moved into operative position.

There are two spools of roping therefore'in the frame simultaneously for each group of spindles fed by a 'givenjack spool, one'of which is in operative position, while the other is in its temporary position at the upper end of the brackets from where it may be moved into operative position when the other spool has become exhausted.

A gate or switch is formed in the vertical slots which receive the gudgeons, preferably the spool gudgeons to be removed laterally 7 from their respective slots without lifting the spool to the full height of the slots, and thereby enabling the operative to remove readily an empty spool from the spinning machine, and thereafter place a full spool in operating position. The exact manner in which this is done will appear more fully hereinafter.

In the drawing:

Fig. 1 is an end elevation of a portion of a spinning frame embodying the invention having two rows of jack spools in which the jack spool at the left of the machine is shown substantially exhausted of roping, while the spool at the right is shown with a full mass of roping thereon.

Fig. 2 is a side View showing one of the brackets and a portion of adjacent ends of the jack spoolswhich are supported thereby.

Fig. 3 is a view similar to Fig. 1 illustrating the portion of a spinning machine in which the invention is adapted to a machine having a single row of jack spools.

Fig. 4 is a cross section on line 1 4 Fig. 1.

Only those elements of a spinning machine which relate to the principles of the invention will be illustrated and described. The remaining elements are or may be of a construction commonly employed in such spinning machines. clear conception of the invention, a particular embodiment thereof is illustrated herein in which a pair of rolls 1 receive the roping from the jack spools and deliver it to the drawing and spinning mechanisms not shown. The roping is fed to the rolls 1 from horizontally-disposed jack spools 2 which are in engagement with and rotated by the usual driving drums 3 journalled in the upper section of the main frame 4; of the machine, and driven by the usual or any suitable driving mechanism not shown herein. While two rows of such spools and driving drums are shown in Fig. 1, a single row of jack spools may be employed as shown in Fig. 3. The latter construction will be described hereinafter.

The jack spools 2 are placed end to end throughout the length of the machine and are provided with gudgeons 5 whch project into substantially vertical slots 6 in especially-constructed brackets 7 which are secured to the main frame 4.. The slots 6 preferably extend completely through the brackets as illustrated in the drawing and serve as journals for two adjacent gudgeons or independent slots may be formed on each face of the brackets. The slots are of sufiicient length to retain a jack spoolhaving a full mass of roping thereon, and to permit the spool to move downward until the roping thereon is exhausted. The slots 6 are open at their upper ends and extend somewhat beyond the highest running position of the spool gudgeons. The slots 6 therefore divide the upstanding portion of the brackets 7 into two leg sections, an inner leg section 8 and an outer leg section 9.

The leg sections 9 are extended upward and outward beyond the upper extremity of the leg sections 8 to form arms 10, the outer ends of which are provided with notches or bearings 11 adapted to receive temporarily the gudgeons of a full spool of roping as shown in Fig. 1. The upper face of the arms 10 constitute a guiding surface 12 over which the gudgeons of the full spool move when it is moved into operative position.

-A particular feature of the invention is a In order to present a full and gate or switch 13 which may be situated at any desired point along the slots 6, but preferably is situated at a point on the slots slightly above the spool gudgeons when the spool is in its highest running position. The gate may be of any suitable construction opening outwardly toward the sides of the machine. The gates 18 are so constructed that the gudgeons of the spools maybe removed laterally from the'slots 6 without lifting the spools out of the upper ends of the slots, and function also to retain the gudgeons in the slots when the full spools of roping are moved from their temporary position into running position. One'method of accomplishing the latter result is to provide a deflector plate 14 which projects outward-and upward at an angle from the'lower edge of the gate 13. Should there be a tendency of the gudgeon to come out of its slot when the spools move downward by gravity into their running p0- sition,the gudgeons will engage the deflector plate 14 and will be guided again into the slot.

If a single row ofspools and driving drums are used as shown in Fig. 3, a single bracket 15 is secured upon the frame of the spinning machine at the junction of adjacent jack spools to receive the gudgeons thereof. The brackets 15 are provided with vertical slots 16 to receive the gudgeons of the jack spools. The brackets 15 are provided also with an upward and outward extending arm 17 in the outer end of which is formed a notch or bearing 18 to receive temporarily the gudgeons of a full spool of roping. The arm 17 serves to guide the full spool from the notch 18 to the slots 16 in the same manner as above described in connection with the brackets 7. The slots 16 are provided with gates 19 similar to the gates 13.

While a single gate is shown for each bracket there may be provided, however, two gates in each bracket one for each adjacent gudgeon on adjacent spools which in the latter case would permit both gudgeons of each spool .to be removed laterally outward in removing the spools from the machine.

It is common practice in operating machinesof the type disclosed herein to lift the full spools of roping into their temporary positions having their gudgeons in. the notches at the ends of the arms 10 of the brackets by means of special roping carriers designed for this purpose. The spools are removed then from the notches 11 and permitted to move down the guiding surfaces 12 through the slots 6 and into running position with the mass of roping engaging the driving rolls. This preliminary procedure takes place when a machine is put initially into operation. After the roping ends are threaded through the spinning mechanism and the machine is ready for operation, another full spool of roping is lifted by means of the usual carrier into its temporary position atithe ends of the arms 10.. A full spool of' roping is in readiness therefore to replace the spool which is in running position when it becomes exhausted. g

Before putting a full spool of'roping into operative position the empty spool must be removed. Prior to the present invention this was a difiicult operation requiring the services ofa tall muscular operativewho, in op erating a machine employing a double row of jackspools', had to lift the empty spool until its'gudgeons emerged from the open ends of their respective slots, and thence over any other encumbrance at the top of the machine. Likewise a considerable amount of unnecessary labor was involved in removing the empty spool and replacing a full one in machines of the type illustrated in Fig. 3. It was necessary in these machines for the operative to remove the empty spools by lifting them while standing at the right-hand side of the machine in I Fig. 3 until the gudgeons thereof emerge from the open ends of the slots. The operative then had to go to the left side of the machine to move the full spool into its running position.

The present invention eliminates much of the time and labor involved in the above described operation. In a machine embodying the principles of the invention full spools of roping are lifted into position by the usual carrier in the manner above described. The machine then is prepared for operation and yarn is spun until the roping upon the spools becomes exhausted.

The operative now must remove the empty spools from the machine, an operation which the present invention greatly expeditesf In the construction in which a single ate 13 is provided for each spool, the spool is removed by liftingone end thereof and removing its gudgeon laterally outward through the gate as shown in dotted lines at the left side of Fig. 1. The other gudgeon' then may be removed from its slot by a slight longitudinal movement of the spool. If a gate is provided for both .gudgeons ofthe spool both of its ends may be removed laterally outward toward the operative. The full spool resting in its temporary position then is moved along-the arms 10 and thence into running position.

The replenishing operation just described may be accomplished easily by the operative,

while standing in a given position for each spool, and the renewal of roping on the entire machine may be done by going successively from spool to spool once around the machine. In the type of machine employing a single row of jack spools the renewing of roping is accomplished in the manner de scribed above by making one trip along one side of the machine.

Because of the fact that the operative is not required to lift the spools over the topmostlimits of the brackets while reaching acrossthe machm-e' in an awkward posltlon Having thus described the invention, what is claimed as new, and desired to'be secured by Letters Patent, 1s: r
